Multiplication of the left and right sides of Equation 5.5.1 by the molar mass in g/mol ( M) of the gas gives ρ = g L = PM RT This allows us to determine the density of a gas when we know the molar mass, or vice versa. cygwin exception
Determine the mass in grams of 6.65 x 10^21 atoms of barium
Number of Atoms = (Given Mass/Molar Mass) * Avogadro’s Number. Number of Atoms = (78/40.078) * 6.02 * 10^ {23} Number of Atoms = 1.9462 * 6.02 * 10^ {23} Number of Atoms = 1.171 * 10^ {+24} For further verification, you can let this grams to atoms calculator do that for you in seconds. Ver más Whether you are going to convert grams to atoms or vice versa, you must have a sound knowledge of the Avogadro’s Number. So let’s define this chemical term first: Ver más If we rearrange the above expression, the resulting one is can be used to convert atoms to grams and is as below: Ver más In chemistry, carrying out various to and fro conversions makes the calculations very easy.
